Sorry,made a mistake thought this was another topic about removing bird poo.

As the article says its been around a while
I looked at it before doing Jonny
You need to be carrying Ethanol & DI water around to refill the charge cooling injection tank
If it runs out it allegedly disables the supercharger, being as its belt driven I'm not sure how
I do love a supercharger thoug
But none of the kits offered ever post details of how the control the fuel mix or deal with the loss of charge cooling
So I'm out

[DB9VolanteDriver]

Superchargers can be clutched in and out electromagnetically, but I suspect that in this case it is probably a simple bypass valve. Don't see any need to carry anything around with you, in that case. Simply top off the tank at home.

At the worst, you simply have no supercharging if the tank runs dry, no?

They had a stand at Brands last year at the 100 year anniversary weekend. Had a good chat with them. Got offered a track session with them as well. Turned them down in case I really liked it.

Do not worry avinalarf, the pigeons flew away before any toiletry activity, because the cat was amongst them.

The charge cooling can be taken care of by the water injection alone at low boost levels, and fuelling can be controlled by the original ECU as long as the injector duty cycle does not exceed about 90%, if it does, using a larger injector and remapping the ECU should take care of that. If remapping, then ignition timing can be altered also.

If the supercharger is driven by an AC compressor type clutch, then it would be simple to deactivate it with a water level sensor, just like the type typically installed in windscreen washer bottles.

Yep, us too. That was our second encounter. They tagged along on a dealership drive-out event last April & had the bonnet up at every opportunity so that curious not-so-little boys like Rob would be lured into peering in & being given the spiel. I don't think the dealership in question had latched onto what was going on as surely they wouldn't have wished to promote such a mod?

Here's what was under the bonnet

Oh happy joy...

Another supercharger thread.

I always love the way that these threads descend into something close to the lowest circle of hell once anyone asks any questions about reliability, durability, testing or engineering. Or even a warranty.

I might even repeat my standing offer of a charity donation on this if the people behind this show up...

Morning, how's sunny Australia?
From memory they were using the car everyday, and had done >20k miles on it. So as a one off sounded durable, with lots of testing and enginering. Did ask about a warranty on the engine, not just the supercharger / upgrades.......

Interesting to see the different directions people take these cars, the challenge with forced induction will be proving and / or guaranteeing overall package reliability. 50k miles is a positive indicator, but surely the power will be over stressing some of the drive chain components?

I had a Honda S2000 that I took from 240 BHP to 425 BHP with a 12 psi supercharger system. With stock drive train and brakes it was no issue over 30k miles. Some US guys ran them for over 120k miles (at 6 psi boost)
Aftermarket blowers do tend to be a lot more reliable than after market turbos because the boost slowly builds directly proportional to the revs, unlike a turbo.
The Honda had a LOT of people fitting the kits and doing the miles.
Having the developer claim they have done 50k miles doesn't mean they were trouble free miles
When I did the S2000 I data logged air/fuel ratios (AFR) and inlet air temps continuously, with out this data you simply cannot tell how safe the conversion is. Some simply rely on the knock control working but adding various bits the the engine can skew this. I'm not a fan of water injection, it is a "lazy" way to charge cool, I'd far rather see some sort of intercooling. It is more reliable and will work ALL the time

With my history I'd be the first to jump on a package of this nature, I've just never seen the AFR and temp data or reliability from a customers car over high mileage. So I'm out

[F1 NDW]

Dont worry AMG will be soon be showing AML exactly how its done!

[williamp]

Surely V8 astons should have two superchargers, not just one...

[900T-R]

Saab did offer a water injection kit for their 99Ts and 900Ts back in the early 1980s... Ford apparently did have the water atomisation jet plumbed into the pipework of their Escort Cosworth for homologation purposes (ERL did deliver 5,000 of them to Dagenham, or so they said at the time) but not the pump & driving electronics IIRC.

Lovely installation of the 2 superchargers. Not sure if the comment was tongue in cheek or not, but it only needs 2 where there is insufficient space to put a single one large enough. Clearly they could have fitted a larger one atop the engine, but hardly subtle, would look like an American Hot Rod.

Love it or not, that is a neat installation.

That car and engine had completed 60,000 miles when I spoke to them at Brands Hatch. It had not suffered any reliability problems whatsoever. I was told that any engines biggest problem is heat! That engine ran cool hence the reliability. I was actually offered a loan of the car but declined. One thing for sure it was Bluddy Quick .

[bogie]

great news if you can get a bolt on kit for £15K with an engine warranty, that would be really tempting

but I bet its more like £20k and warranty only on SC parts ....Id rather not risk spending £20k and killing my engine 6 months later....

Anyone got the latest updated details on this SC kit ?
